Tachyon Network
In the Tachyon network, bi-directional
communications are carried over satellite, eliminating the necessity of
the end-user terrestrial Internet connections that are inherent with
one-way satellite systems.
Traffic over the Tachyon satellite
network consists of both the broadband, outbound "forward" channel from
the satellite Gateway to the TAPs, and the multiple inbound "reverse"
channels from the remote TAPs to the Gateway.
The forward
channel utilizes standard digital broadcast technologies to simultaneously
optimize satellite bandwidth efficiency and lower TAP costs. The Tachyon
communications technology supports forward channel data rates of 45Mbps.
The reverse channel utilizes a multi-carrier TDMA (time division multiple
access) methodology to provide connectionless operation and maximize
bandwidth allocation. The reverse channel supports transmission rates of
256Kbps per TAP. System wide capacity for multiple access is typically
6Mbps to 8Mbps.
